Lyiene Belesford

She is overwhelmed by the dungeon's initial boss monster and loses her virginity to the tentacle monster. Will saves her before the monster can finish her off, which makes her both grateful to Will for saving her life and upset that he saw her naked in a compromising position.

When Lyiene finds embryos in the dungeon, she needs Will's sperm through sexual contact which is a requirement to awaken the familiar within.

Lyiene was lured to the island as her heart was the final ingredient required to finish Alice's ritual of immortality and eternal youth. Will's unexpected intervention ruined the carefully laid plan, but the journey to the dungeon's depths gave Lyiene the strength to overcome the final obstacle and complete the commission set to her.

After the final battle she leaves the island together with Will to report her findings to her teacher. She then travels together with Will as partners and full-fledged adventurers.
